FIG. 3 is a block diagram illustrating a software configuration of theimage processing apparatus 103 according to the present exemplaryembodiment.

Each software (module) described below is stored as firm software in theHDD 204 of the image processing apparatus 103, and read to the RAM 202to be executed by the CPU 201. Further, each software is stored asfirmware 350 in the HDD 204 of the image processing apparatus 103, andread to the RAM 202 to be executed by the CPU 201.

In FIG. 3, a real time operating system (OS) 301 provides variousresource management services and a framework optimized for controlling abuilt-in system for software operated thereon.

The various resource management services and the framework provided bythe real time OS include multitask (thread) management for managing aplurality of processing execution contexts by the CPU to operate aplurality of processes substantially in parallel, and intertaskcommunication for realizing synchronization or data exchange betweentasks. They further include memory management, interruption management,and a protocol stack in which various protocol processes such as variousdevice drivers, a local interface, a network or communication aremounted.

A controller platform 302 includes a file system 303, job-device control304, and a counter 305.

The file system 303 is a mechanism configured in a storage device suchas the HDD 204 or the RAM 202 to store data. The job-device control 304controls hardware of the image processing apparatus 103 and a job thatutilizes basic functions (printing, scanning, communication, and imageconversion) mainly provided by the hardware of the image processingapparatus 103. The counter 305 manages an expiration date of eachapplication and counter values of printing and scanning stored in theSRAM 209.

A system service 306 includes application management 308 and windowmanagement 309. The application management 308 is a management modulefor installing, uninstalling, starting, or stopping applications 310 to314. The window management 309 is a management module for controlling adisplay order of application windows included in the applications 310 to314.

An application platform 307 is middleware for utilizing the mechanismsof the real time OS 301 and the controller platform 302 from theapplications 310 to 314.

The applications 310 to 314 are application software for realizingvarious business models by using functions provided by the applicationplatform 307.

The application 310 has a menu function of selecting each application.The application 311 for a web browser provides a web browser function ofbrowsing a web server.

The application 312 for copying provides a copying function of copyingthe paper document. The application 313 for a facsimile provides afacsimile function of transmitting data.

In the present exemplary embodiment, each application that has receivedthe ACT 104 through the login notification executes screen generationprocessing according to the user who has logged in based on itsinformation. In the present exemplary embodiment, the login notificationincludes the ACT 104 acquired from the SA according to user'slogging-in. However, the login notification can include otherinformation such as an ID or a password for identifying the user, or alogin context indicating the success of logging-in.

As an example of a function limitation according to the login user,processing in the case of a limitation where the login user is inhibitedfrom using the web browser, executing color copying, and manuallyinputting a facsimile number, will be described.

In this case, the application 310 for the main menu processes the menufunction to inhibit the login user from selecting the unusable webbrowser. Specifically, an icon on the menu screen is shaded or notdisplayed to inhibit a transition of a screen for executing theapplication 311 for the web browser. The application 312 for copyingexecutes processing to inhibit selection of any color copy button. Theapplication 313 executes processing to inhibit input of a new facsimilenumber while permitting only selection from an address book.

The application 314 for logging-in is authentication software forauthenticating the user. The application 314 displays a login screen forreceiving logging-in to the image processing apparatus 103 on theoperation unit 212. Then, the application 314 transmits a user name anda password that are input by the operation unit 212 to the SA 102, andexecutes login processing based on the authentication result. Theapplication 314 displays an error when the authentication fails, andexecutes a series of processes after the authentication when theauthentication succeeds.

Referring to FIGS. 4, 5A, 5B, and 6, a limitation method according tothe first exemplary embodiment will be described.

FIG. 4 illustrates an example of a UI screen displayed in the operationunit 212 illustrated in FIG. 2. This example corresponds to an initialapplication setting screen.

In FIG. 4, an initial application setting screen 401 is output from thewindow management 309 to the operation unit 212. The window management309, which is stored as the firmware 350 in the HDD 204 of the imageprocessing apparatus 103, is read to the RAM 202 to be executed by theCPU 201.

On the initial application setting screen 401, a list of applicationsregistered in the window management 309 is displayed. An application isselected, and set as an initial application in the HDD 204 by pressingan OK button 402.

In the present exemplary embodiment, the initial application is anapplication selected, by the user, from the list of applicationsdisplayed on the screen illustrated in FIG. 4. The set applicationbecomes a screen displaying a state where an application is selected forthe first time after user authentication. Specifically, this is anexample where after the user authentication, a copying selected state isdisplayed as an initial screen in the operation unit 212.

In the present exemplary embodiment, the initial screen is a screen towhich a login screen is changed when logging-in is received via a screen(a login screen) used for the user to log in to the image processingapparatus.

FIGS. 5A and 5B illustrate, respectively, a login processing sequence inthe image processing apparatus according to the present exemplaryembodiment.

Hereinafter, processing when the initial screen is displayed in theoperation unit 212 after a registered user logs in and a loginnotification is transmitted to each application will be described indetail. In the present exemplary embodiment, the firmware 350 concerningthe login processing is stored in the HDD 204 of the image processingapparatus 103, and read to the RAM 202 to be executed by the CPU 201.

As illustrated in FIG. 5A, in the first exemplary embodiment, theapplications are divided into two groups, namely, a first group and asecond group, to be managed according to execution environments andapplication characteristics.

The applications belonging to the first group are for executing imageprocessing, and include the application 314, the application 313 forexecuting the facsimile function, and the application 312 for executingthe copying function.

Similarly, the applications belonging to the second group are forexecuting display processing, and include the application 310 fordisplaying the main menu and the application 311 for executing the webbrowser.

When the application belonging to the first group needs a loginnotification, the application belonging to the first group and needingthe login notification must register a login notification event in theapplication 314 for logging-in.

When the application belonging to the second group needs a loginnotification, the application belonging to the second group and needingthe login notification must register a login notification event in thewindow management 309.

The application 314 for logging-in transmits the login notification tothe application belonging to the first group, while the windowmanagement 309 transmits the login notification to the applicationbelonging to the second group. In other words, main units (applications)that transmit the login notification are different between the firstgroup and the second group.

The application 314 for logging-in is configured beforehand to transmitthe login notification to the window management 309.

FIG. 5A illustrates a sequence when the initial screen is set in theapplication 314 for logging-in on the initial application setting screenillustrated in FIG. 4. Processing of steps S501 to S504 will now bedescribed.

In FIG. 5A, in step S501, after reception of user's logging-in to theimage processing apparatus 103, the application 314 for logging-intransmits a login notification to all the applications belonging to thefirst group irrespective of which application has been set on theinitial screen. Specifically, the application 314 for logging-intransmits the login notification to the facsimile application 313 andthe copying application 312, both of which belong to the first group.Then, after completion of transmission of the login application to theapplications belonging to the first group, the application 314 forlogging-in transmits the login notification to the window management309.

In step S502, the window management 309 acquires the initial screensetting set in FIG. 4, and determines whether the initial screen is theapplication belonging to the first group or the application belonging tothe second group. This determination is for judging whether the loginnotification has been transmitted to the application set on the initialscreen when the window management 309 receives the logion notification.

In FIG. 5A, the initial screen is the copying application 312 (i.e., theapplication belonging to the first group). Thus, in step S503, thewindow management 309 changes the screen of the application 314 to thescreen of the application 312. At this time, transmission of the loginnotification to the application 310 for the main menu and theapplication 311 for the web browser is not completed yet.

Thus, the present exemplary embodiment is advantageous in that theinitial screen can be displayed before the login notification istransmitted to all the applications, and the time until the display ofthe initial screen after the logging-in can be shortened.

However, when the initial screen is displayed before the loginnotification is transmitted to all the applications as in the case ofthe present exemplary embodiment, the following situation may occur.That is, the user may instruct a screen transition to another screen(e.g., a screen displayed by the application 310 for the main menu orthe application 311 for the web browser) after the initial screen hasdisplayed.

Accordingly, the window management 309 inhibits the screen from changingto an application that has not received the login notification yet,namely, the application 310 for the main menu or the application 311 forthe web browser. This is protection processing for preventing any screennot based on information of the logged in user from being displayed, dueto the screen transition of an application that has not received thelogin notification yet.

Then, the window management 309 transmits the login notification to theapplication 310 for the main menu and the application 311 for the webbrowser. Then, in step S504, the window management 309 permits changingto the screen of the application 310 for the main menu or theapplication 311 for the web browser.

FIG. 5B illustrates an example of a sequence when an initial screen isset in the application 310 for the main menu on the initial applicationsetting screen illustrated in FIG. 4.

In step S511, after detection of user's logging-in, the application 314transmits a login notification to the window management 309 in the samesequence as that illustrated in FIG. 5A. In step S512, the windowmanagement 309 executes determination similar to that of step S502.

In this sequence, since the initial screen is set in the application 310for the main menu, the window management 309 transmits the loginnotification to the application 310 for the main menu. Then, in stepS513, the window management 309 changes the screen of the application314 for logging-in to that of the application 310 for the main menu.

At this time, transmission of the login notification to the application311 for the web browser is yet to be completed. Thus, the windowmanagement 309 inhibits screen changing to the application 311 for theweb browser. Then, the window management 309 transmits the loginnotification to the application 311 for the web browser. Then, in stepS514, the window management 309 permits changing to the screen of theapplication 311 for the web browser.

FIG. 6 is a flowchart illustrating a control method of the imageprocessing apparatus according to the present exemplary embodiment.

This example corresponds to the login processing example of the imageprocessing apparatus 103. The firmware 350 concerning the loginprocessing according to the present exemplary embodiment is stored inthe HDD 204 of the image processing apparatus 103, and read to the RAM202 to be executed by executing one step by the CPU 201. A main unitwill be described as a corresponding application.

Hereinafter, in the present exemplary embodiment, an example where aspecific application belonging to the first group and registered by theuser is the application 312 for executing image processing correspondingto a copying function will be described. However, the application can bethe application 313.

In step S601, the application 314 detects logging-in. Then, in stepS602, the application 314 transmits a login notification to theapplication of the first group. In step S603, the application 314transmits the login notification to the window management 309.

In step S604, the window management 309 acquires initial screen setting.In step S605, the application of the initial screen determines whetherthe application belongs to the first group. This determination isexecuted by the procedure of step S502. Specifically, the windowmanagement 309 has an identifier of the application and registration asto which group the application belongs received at the time of startingeach application, and executes the determination based on thisinformation.

When the window management 309 determines that the application does notbelong to the first group (NO in step S605), the processing proceeds tostep S606 to transmit the login notification to the application of theinitial screen. Then, the processing proceeds to step S607.

On the other hand, when the window management 309 determines that theapplication belongs to the first group (YES in step S605), theprocessing directly proceeds to step S606.

In step S607, the window management 309 changes the screen to theinitial screen. In step S608, the window management 309 inhibits screenchanging to an application yet to receive the login notification.

In step S609, the window management 309 transmits the login notificationto the application yet to receive the login notification. Instep S610,the window management 309 permits screen changing to the application towhich the screen changing has been inhibited in step S608 to end thisprocessing.

According to the present exemplary embodiment, when the loginnotification has been transmitted to the application of the initialscreen, the initial screen can be displayed before completion of theentire login sequence. As a result, the logging-in time can be shortenedwhile configuring a correct screen based on information of the loginuser for each logging-in.

The present exemplary embodiment has been described assuming that theapplication for executing the image processing belongs to the firstgroup and the application for executing the display processing belongsto the second group. However, in addition to this division ofapplications, the applications can be divided between the first groupand the second group according to which software execution environments(operation environments) the operations operate in.

More specifically, a JAVA (registered trademark) execution environmentrealized by a virtual machine is constructed as an execution environmentfor another included system on the real time OS 301 illustrated in FIG.3. Then, applications operated on the real time OS 301 (first executionenvironment) are set as applications belonging to the second group andapplications operated on the JAVA (registered trademark) executionenvironment (second execution environment) are set as applicationsbelonging to the first group.

Specifically, the application 314 for logging-in, the application 312for copying, and the application 314 for the facsimile are operated inthe JAVA (registered trademark) execution environment. The application311 for the web browser and the application 310 for the main menu areoperated on the real time OS. A method for transmitting a loginnotification to the applications belonging to each group and screendisplay control to the initial screen are carried out based on thesequences described above referring to FIGS. 5A and 5B.

The group division based on the difference in execution environmentbetween the applications to be executed provides the following effects.

In this case, it is presumed that the logging-in application forreceiving user's logging-in operates in the JAVA (registered trademark)execution environment. The logging-in application operated in the JAVA(registered trademark) execution environment always transmits a loginnotification to the other applications similarly operated in the JAVA(registered trademark) execution environment irrespective of initialscreen setting, and to the window management 309 operated on the realtime OS 301. Thus, transfer of data (login notification) between aplurality of different software execution environments can be reduced toa minimum.

In the first exemplary embodiment, the timing of determining the initialscreen setting is after the transmission of the login notification tothe application of the first group. Thus, in the first exemplaryembodiment, when the application set on the initial screen belongs tothe second group, the time until the displaying of the initial screencan be shortened. However, in the first exemplary embodiment, when theapplication set on the initial screen belongs to the first group, theeffect of time shortening cannot be provided, or limited.

Next, a second exemplary embodiment will be described. A basicconfiguration of an image processing apparatus according to the secondexemplary embodiment is similar to that of the first exemplaryembodiment illustrated in FIGS. 1 to 4. A feature of the secondexemplary embodiment will be described.

FIG. 7 illustrates a login processing sequence in the image processingapparatus according to the present exemplary embodiment.

This is an example of a sequence when an initial screen is set in anapplication 312 copying on the initial application setting screenillustrated in FIG. 4. In the present exemplary embodiment, a firmware350 concerning the login processing is stored in a HDD 204 of the imageprocessing apparatus 103, and read to a RAM 202 to be executed by a CPU201.

First, in step S701, after detection of user's logging-in, anapplication 314 transmits a login notification to a window management309.

In step S702, the window management 309 acquires initial screen setting.In step S703, the window management 309 transmits the login notificationto the application 312 for copying.

Then, in step S704, the window management 309 changes the screen of theapplication 314 to the screen of the application 312 for copying.

In other words, the second exemplary embodiment is different from thefirst exemplary embodiment in that after reception of user's logging-in,the application 314 for logging-in transmits the login notification notto the application 313 for the facsimile but to the window management309.

The window management 309 transmits the login notification to anapplication (application 312 for copying in the example illustrated inFIG. 7) set on the initial screen, and controls displaying of theinitial screen before transmission of the login notification to theother applications.

As a result, a higher speed can be achieved for the screen displayingirrespective of what type of application the application set on theinitial screen is.

At the time of displaying the initial screen, transmission of the loginnotification to the applications other than the application 312 forcopying is yet to be completed. Accordingly, the window management 309inhibits screen changing to those other than that of the application 312for copying.

Then, the window management 309 transmits the login notification to theapplication 313 for the facsimile, the application 310 for the mainmenu, and the application 311 for the web browser. Then, in step S705,the window management 309 permits screen changing to those other thanthe application 312 for copying.

FIG. 8 is a flowchart illustrating a control method of the imageprocessing apparatus according to the present exemplary embodiment.

This example corresponds to the login processing example of the imageprocessing apparatus 103. The firmware 350 concerning the loginprocessing according to the present exemplary embodiment is stored inthe HDD 204 of the image processing apparatus 103, and read to the RAM202 to be executed by executing one step by the CPU 201. A main unitwill be described as a corresponding application.

In step S801, the application 314 detects logging-in. Then, in stepS802, the application 314 transmits a login notification to the windowmanagement 309. In step S803, the window management 309 acquires initialscreen setting. Instep S804, the application 314 transmits the loginnotification to the application of the initial screen (application 312for copying in the example illustrated in FIG. 4).

In step S805, the window management 309 changes the screen to theinitial screen. In step S806, the application 314 inhibits screenchanging to applications yet to receive the login notification, namely,applications other than the application of the initial screen.

In step S807, the application 314 sequentially transmits the loginnotification to the applications yet to receive the login notification.Then, in step S808, the application 314 permits screen changing to theapplications to which the screen changing has been inhibited in stepS806.

According to the present exemplary embodiment, irrespective of groups,the login notification is first transmitted to the application of theinitial screen, and the screen is changed. Thus, better effects can beprovided.

Each process of the present exemplary embodiment can be realized byexecuting software (program) acquired via a network or various storagemedia by a processing apparatus (CPU or processor) such as a personalcomputer (computer).

The present invention is not limited to the exemplary embodiments.Various changes (including organic combinations of the exemplaryembodiments) can be made based on the gist of the present invention,which are within the invention.
